After my initial load, "allow-same-origin" is removed and then I load file_iframe_sandbox_a_if9.html, which attemps to call a function in window.top. This should succeed since the new sandbox flags shouldn't have taken affect on me until I'm reloaded. <iframe id='if_9' src='about:blank' height="10" width="10"></iframe> </body> </html>
